G'day,
Jerry, I copied your post to Derek and got the
following reply. Feel free to answer his questions, but go easy on the
strong language (ie refrain from using or implying "stealing" or similar terms)
or your future posts will be edited by me or Michelle.
regards,
Rob
WOW -
The Jerry Dycus name rings a very, very faint bell, which I
could not begin to put into any
context and I have no idea what feature he
is talking about. Stealing is a strong word. He
must have
been dwelling on this one for a long time. - though it seems I may have
unwittingly done him a favor.
I can honestly say that I have always
been in the position of having more ideas of my own I
am seeking the chance
to try, so cannot imagine wanting or needing to steal someone
elses.
At the same time, we do not live in a vacuum and
ideas do circulate. You only have to look
how the typical new cat
designs have come to a common style. It can be clients coming
with
ideas. Some ideas are obvious but if used I still like to give
credit in talking about
them. An example of this is in some of
the prop arrangement in some on our power cats.
The way the
water comes back onto the props is a fairly obvious way, but it is one that was
certainly most widely used by Malcom Tennant. A client of mine came to
me with his
outline drawing of what he wanted, in which this feature was
included and was appropriate -
which I have said to lots of clients.
There are times when ideas do get copied, but where do you start and
finish. An example
which springs to mind - John
Shuttleworth is known for his flaired hull shape on his cats. He
talked of
watching the water flow around a flaired hull. That first hull was a
Kelsall tri which
he built before getting into designing. I don't have a
problem. How many others have copied
since? I first used the idea on
the inside only of a cat and on 37 ft, tri., both in 66.
Jerry - working on a flat table 25 years. Wonder where that idea
came from? Bet he uses
foam too.
By 76, we had a
lot of designs under our belt - one, two and three hulls - including
Proas.
At 32 foot - we had the Kelly 32 - one of a similar
range. 3-4 built, one in ply.
We did a Suncat 32 - built in
Argentina only. Cannot believe it would be either of these. I
believe
we did one other 32 design of which none got built. Would need
reminding on this
one. Some 200+ different Kelsall designs have flowed
under the bridge since then.
So - Jerry, I am sorry if
something that I did in a design was taken by you as taking an idea
of
yours. However, I can assure you I was/am not aware of
it. You do not tell us what the
feature was.
Likewise, I
could say I got into design via Arthur Piver. We discussed hull shapes
amongst
other things on his visits to Texas while I was building my
first. He was adamant that he had
it absolutely right. My experience
told me otherwise. The evening before the start of the
1966 Round
Britain Race, I was told in strong terms, that I could not design trimarans -
that
was Pivers province. Clearly, without having sailed Piver
trimarans, there would probably
never have been a Kelsall. Proas -
Dick Newick can rightly claim to have set the pace in
getting the first
modern proa to the water. I cannot imagine that Dick would claim
exclusivity. I know that my interest was sparked by an article in the
Amateur Yachting
Research Society mag (probably mid sixties) - by, I
believe, a New Zealander and a name
that just sticks in my memory along with
the drawing on the front cover - R.S.J. Taylor.
Oh - and as I have said
to you Rob a few times and on the multihull-boatbuilding forum - I
have no
plans to go back to designing proas. Far, far too many of our own ideas
still to
work on. I look forward to Proa discussions though. We
learnt a lot and I have felt that the
arrangement was never fully tested -
before being banned by the Royal Western Yacht Club
from their races.
Too many capsizes while solo sailing - of which I contributed one. - I will
add my little tit bit. It was offshore, in the N. Sea and I was picked
up by another proa!!
There are a considerable number of boat
builders using flat panels from a table. ( Lots of
tables have been built in
NZ and Australia since I came to NZ). However, KSS is a lot
more
than this. I could write a book on the step by step process we have
gone through
since building that first full size table in 1973.
When resin infusion came in, it started a
whole new line of
refinements. It is rare for a workshop not to produce something new.
It
may be relatively minor but it all goes into the KSS pot.
I should also state - no I did not invent foam sandwich. It was my
boats which put foam
onto the map. The how was entirely my own
work. No, I did not invent resin infusion.
However, we
have developed and refined the process out of all recognition to where we
started. This has been directed for the way in which we use it.
KSS addresses almost every task in boat building, where we can always
produce the
equivalent of any other design.
And Jerry - let me have
your address. I will send you a video. You really should give resin
infusion a try. For work on a table, I do not believe you would ever want to
go back. It
changes the whole process. True there are times when
you wonder at the set up time.
However, once the resin taps are open
and the whole full foam sandwich panel is infused
half an hour later, there
are no doubts whatsoever that it was all worth while and a lot
quicker for
any panel of any size. The hand laminating was the part I never
looked forward
to in the workshops. Now, it is all fun.
On time, resin infusion is not efficient for small solid glass
panels. It is setting out all of the
glass and foam dry and then
infusing in one, which pays.
Stealing in design would be to take
something that is clearly known as the work of one
designer, particularly
where that designer has produced the orginal novel idea and put a lot
of
effort into prefecting and promoting it. The Farrier Folding system is
such. When it
comes to styles or layouts it becomes a very grey
area. It is not that unusual either to find
two designers
have arrived at the same idea at the same time. ie the time was right for
that
idea to come to the fore.
KSS belongs to Kelsall
Catamarans.
Best wishes,
Derek.

The short answer is yes, they can be
built
that fast!! Not only that, but I've built them that
way to
80'/25m.
I've been building flat panel FG boats off of
table/flat molds
for 25 yrs.
How I became a multihull designer was when
asking for advice
back in 76? of Kelsell when he stole
the design ideas and showed up 3
months later in
Multihulls Magazine as the Kelsall 32 Cat ;^D.
Expect
your designs, ideas to show up in his plans soon I'd
bet as
his!
At that point I understood if I was good
enough to steal from, then
I could design my own and
did, building over 400 boats, about 40 multihulls
and
6 tacking proas in all masterials. Not that I minded
being stolen
from by a big designer as it's was a kind
of compliment!
Why would you
build a Harryproa or any
sellable boat one off and not take a FG mold off
it?
FG molds don't cost that much and very easy to do.
It's the plug
that takes the work.
Then everyone after would be able to have a
first
class FG one would seem to be a smart business
move?
It takes me less
than 8-10 man-hrs to build a
40'/12m hull in FG including all prep. About
the same
to do my composite monococque Electric car
body/chassis I'm now
doing with molds.
Now with Tortured Plywood/epoxy method I can
build a
40' hull in about 10 hr.
I've also built tortured FG by the same way
I
do plywood/epoxy, making a 32'x7' panels on a flat
mold. This works
fairly well though depends on it
being caught in the right stage of curing,
between 1
and 5 days after being laid up depending on temp,
resin used.
Composite masts can be built that way
too.
While I love strip plank,
I'd never build one
that way because it's too much work and cost.
His
resin infusion is probably too much work.
Not the actual infusion, but all
the prep, afterwork,
costs nessasary. Just pour out the resin and
squeegee
it out, pop on the core, lay up the inside gives just
as good.
Being flat so resin doesn't run down is the
key to making it easy to layup
too besides the outside
being finished by the mold.
Welcome to the world
of fast boatbuilding!
It's where the profit is!!
